Real Clock 200 MHz (QDR).. this one is what could be called your system clock.. it governs everything else..

DRAM:FSB Ratio 5:6.. this one is what links your memory speed to the system clock.. for example.. 5/6s of 200 gives memory speed of 167.. its less than 1 to 1.. it could be called the ram divider..

your cpu speed is a multiple of the system clock.. xxxx x 200.. at least i think it is.. he he

when u speed up the system clock of 200 u speed up everything else.. what reaches its speed limit first could be memory.. fsb bus speed.. or cpu speed..

somehow u have to find out how fast each piece goes.. u do this by slowing other bits down useing dividers or multiplyers.. when u know the limits of each piece u kinda find a compromise for em all.. sometimes to get one bit faster u have to slow down another bit..

I have a feeling the original poster just heard the word overclocking and got excited and wanted to jump right in without even googling the term. If you didn't know what a FSB is, why did you trying to increase it?

A short answer to your question is, open up your BIOS (do a google search for this) and you should be able to change your FSB under Advanced Config Options (search there.)

A better answer is, you should actually do research before trying to do anything to your computer. Try searching "overclocking" and "guide" together in google and you get pretty good introductions.

Overclocking depends not only on the mobo you are using, but the cpu, memory, cooling, and psu. This info, or you doing a little research on what cpu you are using will help. When you OC the fsb, you are overclocking the processor. Make sure that you can get rid of the extra heat. Make sure that you keep the pci/agp/pci-x bus speeds where the already are, or close to it.

Hey wait, everything I learned about OC'ing I learned from this website and forum, read dude, read

You may want to get some faster memory to compliment the processor you are using. If only we knew what hardware you are using on the mobo

My system does not allow bus overclocking from my bios, but I can do it in windows with Clockgen. I first had to identify my ICS chip number which was 954108. You can make small increases until your system stops responding and at that point all you need to do is reboot to fix it. Now you will have to run some sort of stress test once you find a point that seems stable in order to determine if the new overclocked setting is stable.

system
Intel D955XBK
Intel D820 2.8GHZ dual core
1gb corsair valueram 512x2
runs stable at 3.4ghz without buying new memery which i think is the factor as to why it won't go higher

Please spend a few days researching overclocking on your particular motherboard with google and you will get many pointers. Beware there are tons of overclocking snobs out there.

There is a guide for you to read that will explain a bunch of the basics. I suggest reading as many of the guides on that forum as you can before overclocking so you know what you are getting into and how to do it safely. As long as you use small steps and check it as you go you will be relatively safe in overclocking.
